“…This might be used to predict the growth patterns and/or growth potential of the mandible in future studies. Previous studies demonstrated that the condyles were positioned more anteriorly in Class II patients whether they had horizontal 4,10,14,27 or vertical 5 skeletal patterns. In this study, PS increased in the Class II skeletal pattern, but this relationship was not statistically significant.…”

“…The condyle-fossa relationship has varied according to sagittal and vertical skeletal patterns in several studies. [1][2][3][4][5] This study demonstrated that there were only some differences in condylar position inside the glenoid fossa. The condyle was positioned more inferiorly in hypodivergent than hyperdivergent Class II skeletal patterns (Table 4), which was similar to findings of previous studies.…”

“…Therefore, the relationship between condylar position and skeletal patterns should be considered when planning and executing a proper treatment plan for temporomandibular anomalies during orthodontic treatment. 4,5 The optimal position of the condyle in the glenoid fossa is a fundamental question in dentistry. Controversy persists over the clinical significance of condylar position in the temporomandibular joint (TMJ).…”

“…[9][10][11] Nonconcentric condyle-fossa relationships have been associated with abnormal TMJ function. 10,[12][13][14][15][16][17][18] However, in other studies, 4,5,13,[19][20][21][22] the presence or absence of temporomandibular disorder (TMD) did not correlate with the condyle position in the TMJ.…”

“…Some research has noted the influence of occlusion in the condylar process-mandibular fossa relationship, 4,5,10,[13][14][15][27][28][29][30][31][32][33] while others have not. 4,5,13,[19][20][21][22] Studies have found that the condyles were positioned more anteriorly, 4,5,10,[13][14][15]27,28 posteriorly, 27,29,30 intermediately, 27 superiorly 27,28,31,32 and inferiorly 33 in various occlusal, skeletal, and facial relationships. In addition to condylar position, occlusion might be related to the articular eminence angle or slope 13,14,28 and articular eminence height, 14,16,17 or the vertical height of the fossa 13,19,28,31 and anteroposterior and mediolateral thickness of the condylar head.…”

Objectives: To evaluate the condyle-fossa relationship in adolescents with various skeletal patterns using cone-beam computed tomography (CBCT). Materials and Methods: CBCT images obtained in 120 adolescent patients were used for this study. The patients were divided into 3 groups according to 3 criteria: (1) age (early, middle, and late adolescence); (2) facial height ratio or Jarabak quotient (hyperdivergent, normodivergent, and hypodivergent); and (3) ANB classification (Class I, Class II, and Class III). Temporomandibular joint space (TMJS: AS, anterior space; SS, superior space; PS, posterior space; MS, medial space; LS, lateral space), width and depth of the condyle (MLT, mediolateral thickness; APT, anteroposterior thickness), articular slope (ArS) and vertical height of the fossa (VHF) were measured and compared using CBCT. Results: Differences in condyle-fossa relationships were not significantly different between male and female adolescents, but were significantly different (P < .05) between left and right sides. The mean values showed no statistical differences according to age and skeletal pattern. Most measurements in the sagittal view showed that SS was the greatest, and the mean ratio of AS to SS to PS was 1.00 to 1.27 to 1.19, respectively. The mean values of coronal MS and LS were not significantly different. Conclusions: There were almost no statistical differences in the TMJS in adolescents across various factors except between left and right sides.

Objectives This study was designed to investigate the relationship between the morphological structure of condyle and occlusal plane in skeletal Class II malocclusions by imaging measurement. Materials and Methods This study included 65 skeletal Class II adult patients (18–35 years old) who met the criteria, and all were taken with cone beam computed tomography (CBCT) images (skeletal Class II high angle 38 cases, average angle 18 cases, and low angle nine cases). The statistical methods of mean standard deviation, Pearson correlation, and analysis of variance were used to study the correlation between the size of the condyle and occlusal plane in skeletal Class II malocclusion. Results The FMA and SN‐OP between the groups in skeletal Class II malocclusion are considered statistically significant, p < .05 high angle group > average angle group > low angle group, whereas there are significant correlations between FMA, FH‐OP, SN‐OP, and the medial–lateral diameter (MLD) of the condyle, p < .05, showing a negative correlation. The anteroposterior diameter of the condyle has no significant correlation with these angles, and the high‐angle group size is smaller than the other groups. Conclusion In patients with skeletal Class II high angle malocclusion, the MLD and anteroposterior diameters of condyle were smaller than those of average angle and low angle groups, and negatively correlated with the FMA and SN‐OP. That is the steeper occlusal plane, the smaller MLD of the condyle. It suggests whether orthodontists can promote the stability of the morphological structure of the condyle by changing the inclination of the occlusal plane during the orthodontic process.

Objective This study was performed to evaluate the position and morphology of the temporomandibular joint in female patients with skeletal class II malocclusion and to investigate the association between temporomandibular joint disorders and facial types using cone-beam computed tomography. Methods A lateral cephalogram was taken to determine the skeletal class of each participant. Sixty female patients aged 16 to 28 years were divided into high-angle, low-angle, and control groups. The shape of the condyle–fossa was measured and assessed on cone-beam computed tomography images of the 120 temporomandibular joints. Results Some condylar shape measurements displayed statistically significant differences among the groups. No significant differences were found in the length of the condyle, width of the glenoid fossa, or height of the articular eminence among the three groups. The posterior condylar position was more frequently observed in the low-angle group, whereas the anterior condylar position was more prevalent in the high-angle group. Conclusion The present study revealed differences in the condyle–fossa morphology and position in female patients with skeletal class II malocclusion with different vertical facial types.
